lVILLIAMs Inns and WILLIAM OLIVER Ross,

subjects of the King of Great Britain, residing, respectively, at 244Camden road, Camden Town, in the county of London, England, and 1Hillfield avenue, I-Iornsey, in the county of Middlesex, England, haveinvented new and useful Improvements in Siphons for Aerated Liquids, ofwhich the following is a specification.

This invention relates to siphons in which the nozzle and valve seat areformed in a single block generally of porcelain or the like, andparticularly to siphons of the kind shown in U. S. Patent No. 1,049,364of January 7, 1913, granted to W. T. W. Idris, in which the porcelainblock is put into place sidewise through a side opening in the casing ofthe siphon top and is secured in place after it has been thus positionedby means of a collar screwing into the casing and pressing against theunder side of the block.

In the patented siphon above referred to, friction alone was relied uponfor preventing the block from moving sidewise out of the side opening inthe casing. According to the present invention the collar is made toengage a shoulder or similar device on the under side of the block andto thus prevent the block from moving sidewise out of the opening. Wealso provide the block with a shoulder to fit the side opening in thecasing and thus prevent rotation of the block.

Figure 1 is a side elevation and Fig. 2 is a vertical section of a shortlever siphon top constructed according to this invention. Fig. 3 is aplan, Fig. 4; a side elevation and Fig. 5 an underside view of theblock. Fig. 6 is a vertical section of a modification.

a is the vase having the usual split ring (2 around its neck and 0 isthe descending tube.

0? is the casing made in one piece of metal and screwing on to the splitring 6.

e is a cap screwing onto the top of the casing (Z.

f is a porcelain block provided with a nozzle g and having in itsunderside a segmental groove in concentric with the valve seat 6.

j is a collar screwing into the casing d and engaging with the groove h.

. the opening.

70 is a washer interposed between the vase a and the block 7".

Z is the valve carried by the spindle m andoperated by the lever npivoted at 0 and working against the spring p the lower end of whichbears on the washer g surrounding the spindle m.

It will be observed that the groove it provides a shoulder it againstwhich the collar j bears and thus prevents the block from being removedfrom the casing until the collar is disengaged. e prefer to use asegmental groove to receive the collar but any kind of a projection orshoulder may be employed for this purpose. The opening in the casing (Zis just suflicient in size to admit the block, the lower face of whichis on the same plane with the lower wall of The collar j when screwedhome, however, projects above the plane of the lower wall of the openingand the lower face of the block, engages the shoulder h and prevents thewithdrawal of the block.

In assembling the parts the washer q is first put into its recess in thetop of the block f and the latter is put sidewise into the casingthrough the side slot or opening in it. The collar j is then screwed upin the casing until it engages with the groove h and firmly holds theblock in place. The valve stem m surrounded by its spring p is nextdropped in at the top of the casing and the stem is passed through thewasher q and the valve Z is screwed onto it. Lastly the lever 11. andcap 6 are put into place and the whole is screwed onto the split ring7). The block f is provided with shoulders f on opposite sides of thenozzle 9 and these shoulders fit the casing on opposite sides of theside opening therein and prevent the rotation of the block.

Fig. 6 is a vertical section showing the application of the invention toa long lever siphon top. a is the vase, b the split ring and a thedescending tube. d is the tubular casing screwing onto the split ringand e is the cap screwing onto the casing. f is the porcelain block andg is the nozzle having on its under side a segmental groove as before.7' is a collar screwing into the casing aland engaging with the groove.70

is a washer interposed between the vase a and the block Z is the valvecarried by the spindle m and operated bythe lever n pivoted at 0 andworking against the spring 2.

What we claim is 1. In a siphon head, the combination of a casing havingan opening at one side, ablock within the casing and which is insertibleand removable through the side opening and is provided on its under-sidewith a shoulder, a nozzle fixed to the block and projecting through saidopening, and a collar screwing into the casing extending above the planeof the lower wall of the side opening and the lower face of the blockwithin the casing and engaging said shoulder to prevent, sidewisewithdrawal of the block through said opening.

2. In a siphon head, the combination of a casing having an opening atone side, a block within the casing which is insertible and withdrawablethrough said side opening and which has a shoulder engaging said casingat the side of said opening to prevent the rotation of the block, andanother shoulder on its under-side, a nozzle fixed to the block andprojecting through said opening, and a collar screwing into the casingextending above the plane of the lower wall of the side opening andabove the plane of the lower face of the block and which engages saidshoulder on the underside of the block and prevents sidewise movementthereof.
